Pay attention to HOW MUCH MONEY IT COSTS TO MINE ONE BITCOIN ... full Amortization Cost.

AND ... pay attention to HOW MUCH MONEY IT COSTS TO MINE ONE BITCOIN JUST FOR THE ELECTRICITY

Once the amount to be received from a Bitcoin drops below it's electricity costs MOST miners will drop out since they are losing monthly money on every Bitcoin mined. Stay low for long ALL will drop out (most likely)

Full Amortized Cost, ie: the computers, the space they occupy, the manpower it takes to run them, is MORE than just the electricity costs.

IF the amount a miner can get for a Bitcoin is MORE than the electricity cost but less than the full cost most miners will probably keep mining but STOP investing in new equipment.

As more and more miners drop out what becomes of the so called "Public Ledger"?

It is my understanding that for Bitcoin at least, withOUT miners there is NO Public Ledger!! This is a hidden mine field waiting to catch the unwary.

Please correct me if my understanding is WRONG about how the Public Ledger is maintained, but NO MINERS = NO PUBLIC LEDGER as I understand it (thus you can't buy or sell Bitcoins)

As everybody should know after today's Crypto actions, not just the price but the impending collapse of various exchanges, LOTS of money is about to be lost in Crypto World due to bankruptcies of the various exchanges which will cause a LOT of the coins being held by those exchanges to just go POOF!! and disappear.

Going to be a wild ride over the next couple of weeks. Those that are leveraged up may LOSE IT ALL ... AND ... BE ON THE HOOK FOR EVEN MORE MONEY!! (how leverage works)
